Limit with PostGIS is that it uses “Simple features model” - OSM model is way more, not less complex: topology (object element hierarchy/links), versioning, editing metadata, schemaless tags etc - none of them were possible in plain postgis. Only more free data schemas (eg jsonb) are added to since OSM debate over db solutions over 10yrs back, the other things are still not there really.
- ldng 7y agoWell, you've said better than I. IMHO, PostGIS is geared toward building classical GIS databases, while OSM is more a Topological Catalog. If I'm not mistaken, they say so themselves and visual map are just a by-product of geo-referencing "everything". Way more complex and way more harder to work with. Edit: maybe I should have said "higher level geometries" than "more complex". In the sense that OSM "knows" about point and edges and nothing else.
